Medical Xpress / Why do people sacrifice short-term happiness for long-term welfare?
(Medical Xpress)—According to the hedonic principle, people are motivated by the pursuit of pleasure and, conversely, the avoidance of pain. Although there is a great deal of evidence to support this theory of motivation, ...
Phys.org / Researchers demonstrate acoustic levitation of a large sphere
When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) ...
Phys.org / Photonic hypercrystals drastically enhance light emission in 2D materials
Researchers have developed a method for achieving an order-of-magnitude enhancement of the light emission from a class of two-dimensional (2D) materials called transition metal dichalcogenides (TMDs). The large light enhancement ...
Tech Xplore / Tomorrow's clothes may be made with light-emitting e-fabric
(Tech Xplore)—Researchers have fabricated a large-area textile that emits bright yellow light for more than 180 hours. The low-cost, flexible, transparent textile has potential applications in light-emitting clothing, signs, ...
Phys.org / Some types of quantum entanglement cannot be both monogamous and faithful
(Phys.org)—As might be expected, the terms "monogamous" and "faithful" mean something a little different in the quantum world than they do in everyday language. In a new paper, a collaboration of physicists and mathematicians ...
Phys.org / Physicists prepare to detect gravitational waves from neutron star collisions
(Phys.org)—Last February, scientists made the groundbreaking discovery of gravitational waves produced by two colliding black holes. Now researchers are expecting to detect similar gravitational wave signals in the near future ...
Phys.org / High-efficiency color holograms created using a metasurface made of nanoblocks
(Phys.org)—By carefully arranging many nanoblocks to form pixels on a metasurface, researchers have demonstrated that they can manipulate incoming visible light in just the right way to create a color "meta-hologram." The ...
Tech Xplore / High-voltage lithium-ion battery realized with superconcentrated electrolyte
(Tech Xplore)—One of the biggest challenges facing next-generation lithium-ion batteries in electric vehicles is finding ways to further increase the driving range. One way to do this is by increasing the battery voltage ...
Phys.org / CP violation or new physics?
(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. So far, ...
Phys.org / Plant cellulose prevents short circuits in batteries
(Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery's electrodes. There is typically a tradeoff involved, since these separators must simultaneously prevent ...
Phys.org / Researchers chip away at Smale's 7th unsolved problem in mathematics
(Phys.org)—How do you arrange a group of points on the surface of a sphere so that all the points are as far apart from each other as possible? With two points, the answer is easy: place them on opposite sides of the sphere, ...
Phys.org / Researchers generate 3D images using just one photon per pixel (w/ video)
(Phys.org)—Every time you take a photograph, your camera detects more than a billion photons. For a basic one-megapixel camera, that's more than 1,000 photons per pixel. Now in a new study, researchers have developed an algorithm ...
Phys.org / Diamond coupled to carbon nanotube could be used for quantum information processing
(Phys.org)—By carefully placing a tiny piece of diamond within a few nanometers of a carbon nanotube, and then sending an electric current through the nanotube, researchers have designed a device that could one day form the ...
Phys.org / Quantum fingerprinting surpasses classical limit
(Phys.org)—As the saying goes, no two fingerprints are alike, and the same is true for quantum fingerprints. Just as a human fingerprint is only a fraction of the size of a person, yet can be used to distinguish between any ...
Phys.org / 'Quantum' bounds not so quantum after all
(Phys.org)—Quantum bounds are numbers (such as 4, 6, and 2√2) that naturally appear in quantum experiments, similar to how the number π emerges in circles. But just as how π pops up in a wide variety of areas beyond circles, ...
